Move over wallet, cell phone are here

Japanese office worker Satoshi Tada pays for shopping, wins free food and gets store discounts all by waving his cellphone.

"I use it pretty much every day," the 25-year-old said. "You can charge money on it right there if needed, and you don't have to run around trying to find an ATM. You can even get points because it's linked to credit cards."

The world's top firms such as Visa Inc and Nokia are still mostly testing phone use for payments, but in Japan, more than 50 million, or about half of all cellphone users, already carry phones capable of serving as wallets.
